Yeah, I noticed, but when we start replacing the firmware, we'd need to detect somehow when a machine has an old (or only different) firmware. That would imply a versioning scheme and a generic way to read out the firmware version. (CMD_GET_FW_VERSION_BOOT is already a start, but this doesn't help me if I find an unknown hash.) So a CMD_GET_FW_SOMETHING that yields a version string that is similar to the soname of a library would be great. Talking about firmware, I wonder if there is firmware supported needed to solve https://wiki.debian.org/InstallingDebianOn/TurrisOmnia#Power_Management . Didn't look into that deeply yet and probably not high prio given that normally the Turris Omnia will just run 7x24h. Best regards Uwe
